It looks to me the format's auto-tuning to device fails. Try using -t=0 instead of just -t for a really small workload (and thus poor speed). Does it work then? If it does, you can experiment with different values for local and global worksizes like this:
LWS=64 GWS=512 ../run/john -t -form:mscash2-opencl
If that too works, try doubling the GWS figure until you find the fastest value that works fine. Please report back.
